Remove black bars from any video. Fit any video to your entire screen on any video platform — automatically.
UltraWideo is the cross-browser extension that manipulates video aspect ratio to fill your screen. Whether you own an ultrawide monitor (21:9, 32:9), a standard 16:9 display watching 4:3 videos, or anything in between — UltraWideo eliminates black bars and gives you a true full-screen experience.
Why UltraWideo over other extensions?
Unlike alternatives that break on certain platforms or stop detecting videos, UltraWideo is proven to work on all major video streaming platforms, including embedded videos across the web. No "video not detected" errors. No broken layouts on non-video pages. It only activates when there's a video to work with.
▸ Works everywhere — any streaming service, any site with embedded video, any platform. Not limited to a single site.
▸ Blazingly fast — written in plain JavaScript with a tiny footprint. No memory leaks, no background processes draining your battery, no performance degradation over time.

Thank you for adding a setting for the floating pop-up so we can choose if we want it or not, that's all we needed. Switched my rating back to 5 stars. Have been using the extension for years and appreciate it, also appreciate you also listening to the feedback on this one! I will say it would be nice to have a setting to not show "upscale/normal/stretch" text bubble at the top-right each time a page is loaded. It only shows that for a second but it's also showing that right now for every page I visit, including pages without video.
Firefox works fine, one hour later, two hours later. But chrome only works in the beginning. It doesn't work over time. It works again when you restart Chrome, but it doesn't work again after a while.
Perfect for UltraWide Screens
The best upsacler and fit aplication for videos
Needs an option to disable upscale... too many times it randomly switched to it when all I wanted was to stretch the video...
youtube added letterboxing to old music videos, so they look terrible on CRTs. NO LONGER!
Works beautifully in Peacock. Ultrawide video content actually fills my ultrawide monitor perfectly now, instead of being surrounded by a thick black frame on all sides. I can't believe this extension is even needed - how are these services not coded to perform this way on their own? - but I'm so glad it exists! Great job. Thank you, so much. (That said, I don't know where else it works or doesn't, but I'm very happy so far.)
- Claims to work everywhere (and in fact says it is the only such add-on to work everywhere!). - Doesn't work on Hulu, in Chrome or Firefox.
nao funciona no edge
I'm not sure why, but when i do the full screen for 21:9, the screen gets washed out on my Alienware OLED monitor. Other apps doesn't wash out my screen but zooms in too much.
